VISION (PMMA Intraocular lens) (for export)
LENSDIDAR is a unique ISO certified manufacturer of intraocular lens in Iran.
LENSDIDAR designs & manufactures intraocular lenses using CAD-CAM system
VISION I.O.L is lathe cut in single piece clinical quality PMMA (from CONTAMAC CO UK)
VISION IOL is sterilized by ethylene oxide. Quality and valid lifetime of the ‘VISION’ intraocular lenses, in accordance to the International ISO & ANSI standards are controlled throughout the following stages:
A: FIBRE COMPATIBILITY TESTS:
- Mutagenicity (Ames test)
- Chromosomal Aberration
- Validity of sterilization
B: OPTOMECHANICAL TESTS:
- Contrast & Resolution
- Fatigue Test
- Surface quality
In order to be assured of then on-deter mental, nature of there award consumed materials, applied in the mainstream technology for manufacturing of intraocular lenses, vast clinical studies were conducted in SIZX medical center under the super VISION of the French Ministry of health for 400 patients, this research project proved the ease of placement of the lenses, the hygiene as well as the satisfaction of the patient. Additionally, the long -term studies, implemented on rats and rabbits have proved the safety of this product.
C: OPTICAL QUALITY:
Due to taking advantage of the CAD-CAM computer -oriented technology in the design and manufacture of “VISION” intraocular lenses, these optical surfaces posses the least potential rate of fallacy.
The optical quality of these surfaces, have been studied with the state of sensibility of 1/10000 of the interfering rings of 535 nanometer laser beams. Centralization of the optical energy in the focal point of this lens has reached it most potential, and an illustration is formed, free of aureole, and without any distribution and scattering of light beams quality of the passage rate of illustration in the MTF (Modulation Transfer Function) curved lens, and it is resolution rate is measured by the US Air force mire.
D: MECHANICAL POTENTIALS:
Due to benefiting from a precise design and appropriate technology, homogeneity of flexibility, is materializing in the Haptics.
This homogeneity and coordination is up to an extent that following the related force is divided between the two Haptics, and homogenous flexibility, softness, and ease of shaping of each of the Haptics, leads to a supporting surface with a 60 to 70 degrees of inclination, in the eye s 11mm sulcus, easing placement of the lenses.
Eradication of all of the aberrations and wastes, as well as the physical and chemical impacts , are the result of the production processes executed upon the lenses, which manifest the sufficiency of the polishing status VISION lenses.
